Cross Post: Re: Nudges in a Post-truth World

In a recent article in the Journal of Medical Ethics, Neil Levy has developed a concept of “nudges to reason,” offering a new tool for those trying to reconcile medical ethics with the application of behavioural psychological research – a practice known as nudging. Very roughly, nudging means adjusting the way choices are presented to the public in order to promote certain decisions.

As Levy notes, some people are concerned that nudges present a threat to autonomy. Attempts at reconciling nudges with ethics, then, are important because nudging in healthcare is here to stay but we need to ensure it is used in ways that respect autonomy (and other moral principles).

The term “nudge” is perhaps a misnomer. To fill out the concept a bit, it commonly denotes the use of behavioural economics and behavioural psychology to the construction of choice architecture through carefully designed trials. But every choice we face, in any context, already comes with a choice architecture: there are endless contextual factors that impact the decisions we make.

When we ask whether nudging is acceptable we are asking whether an arbitrary or random choice architecture is more acceptable than a deliberate choice architecture, or whether an uninformed choice architecture is better than one informed by research.

In fact the permissibility of a nudge derives from whether it is being used in an ethically acceptable way, something that can only be explored on an individual basis. Thaler and Sunstein locate ethical acceptability in promoting the health of the person being nudged (and call this Libertarian Paternalism — i.e.
